Specific implementation manners

[0020] Now, the present utility model will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Please refer to Figures 1-4 , a mine wastewater and sewage recycling and treatment system, including a primary sedimentation tank 2, a sewage treatment tank 3 and a waste storage tank 4. A first partition wall 5 is provided between the primary sedimentation tank 2 and the sewage treatment tank 3, and a second partition wall 6 is provided between the sewage treatment tank 3 and the waste storage tank 4. The primary sedimentation tank 2 is connected to the sewage treatment tank 3. An overflow tank 31 is provided in the sewage treatment tank 3. A secondary sedimentation tank 32 is formed around the overflow tank 31 through a partition wall. The sewage treatment tank 3 and the overflow tank 31 are in a "return" shape. The overflow tank 32 is connected to an external sewage treatment system through a pipeline; the sewage treatment system discharges the treated water into a water storage tank, and the water storage tank then pumps the water source to the construction site through a lift pump to perform dust removal, equipment cooling, etc. on the site, so as to realize water source circulation.

[0022] The primary sedimentation tank 2 is connected to an external trench 1 and is provided with a sewage discharge pipe 21 connecting to the waste storage tank 4. The primary sedimentation tank 2 and the secondary sedimentation tank 3 are connected through a collecting trough 22, and the height of the collecting trough 22 is higher than the partition wall of the overflow tank 31.

[0023] The trench 1 is arranged at the construction site, and its elevation is higher than that of the primary sedimentation tank 2. The construction wastewater can flow into the primary sedimentation tank 2 through natural flow in the trench 1. After flowing in, the sewage and wastewater first undergo primary sedimentation in the primary sedimentation tank 2. At this time, sand and gravel settle, and the upper liquid enters the secondary sedimentation tank 3 through the collecting trough 22.

[0024] Since the overflow pool 31 is arranged in the secondary sedimentation tank 3, and the partition wall of the overflow pool 31 is lower than the collecting groove 22, the upper clear water flowing through the collecting groove 22 first enters the secondary sedimentation tank 32; as the upper clear water is continuously injected, the liquid level of the secondary sedimentation tank 32 is continuously raised; the raised liquid level gradually flows into the overflow pool 31; at this time, the bottom of the secondary sedimentation tank 32 will again appear dust and other small solid impurities, and the impurities of the sewage entering the secondary sedimentation tank 31 are further reduced.

[0025] Among them, the solid impurities precipitated in the primary sedimentation tank 2 can be pumped into the waste storage tank 4 by a sludge pump or other pump; a small amount of precipitated impurities in the secondary sedimentation tank 32 can be regularly cleaned by an excavator or other equipment, and the cleaned waste is also discharged into the waste storage tank 4, which can collect waste gas.

[0026] The wastewater after secondary precipitation finally enters the overflow pool 31, is pumped into the sewage treatment system by the built-in pump, and is further purified to ensure the recycling of the wastewater.

[0027] Specifically, the collecting groove 22 is two and is symmetrically arranged in the primary sedimentation tank 2, the collecting groove 22 is a U-shaped groove steel, the first partition wall 5 is provided with a through hole, one end of the collecting groove 22 is fixed in the through hole, and the other end is fixed on the inner wall of the primary sedimentation tank 2; in this embodiment, the collecting groove 22 is horizontally arranged, and a detachable filter screen 221 is arranged above the collecting groove 22.

[0028] Further, the surface of the filter screen 221 is provided with a plurality of uniformly arranged filter holes 222, and the filter screen 222 is detachably connected with the collecting groove 22 through bolts 223; wherein the top of the filter screen 221 is raised, and the filter screen 221 can realize the filtering of floating objects on the water surface through the filter holes 222, so as to avoid the floating impurities flowing into the sewage treatment tank 3.

[0029] Since the filter screen 222 is detachable, the filter screen 222 can be regularly detached or replaced, so as to avoid the floating objects blocking the filter holes and affecting the water inlet effect.

[0030] In this embodiment, the sewage treatment system includes a water purification device for stirring and mixing and a dosing cabin for adding reagents, the dosing cabin adds reagents into the water purification device for stirring and purifying water, the water purification device is connected with the water storage tank through a pipeline, the water storage tank delivers the purified water to the construction site through a lifting pump; the purified water can reduce dust at the construction site and cool the drilling equipment such as a drill bit when reaching the construction site.

[0031] Among them, the water purification device is a large warehouse structure, and ordinary stirring devices such as a stirring shaft and stirring paddles are arranged inside; the dosing cabin is a reagent storage container; when in use, the reagents in the dosing cabin are poured into the water purification device, and the reagents and the sewage are further mixed to purify the sewage.

[0032] Since the purified water is construction water, not used as domestic water, the reagent in the reagent cabin is mainly used for removing odor, which can be microbial deodorant, biological enzyme reagent or sodium hypochlorite solution, etc. The microbial deodorant made by microbial fermentation can decompose hydrogen sulfide, ammonia and other odor molecules, which has remarkable effect and is more environmentally friendly. The biological enzyme reagent is made of active bacteria and various natural extracts, which can effectively remove malodor and has sterilization function. The sodium hypochlorite solution can eliminate sulfur methyl and other odor substances. The above reagents can realize sewage purification and ensure the air environment of the construction site. Of course, other reagents with the same effect can also be used.

[0033] As a preferred solution, the liquid level controller is arranged in the primary sedimentation tank 2, the sewage treatment tank 3, the secondary sedimentation tank 32 and the overflow tank 31. The liquid level controller, the controller and the pump machine keep stable signal transmission, control the corresponding pump machine to run through the transmission of pulse signals, and realize remote monitoring of water level and liquid level control. In addition, the primary sedimentation tank 2, the sewage treatment tank 3 and the waste storage tank 4 are provided with a flip cover.

[0034] The design of the flip cover enables the operator to easily enter each tank for inspection, cleaning and maintenance, reducing maintenance time and labor intensity. At the same time, it can effectively prevent accidental falling objects and external objects from entering the tank, thereby reducing the risk of accidents and improving the safety of operation. It can also reduce the odor and gas release of the sewage tank, improve the working environment and ensure the health and safety of the operator. The detachable design enables quick opening in different situations (such as dredging or emergency repair), increasing the flexibility and adaptability of the system. It can also reduce water evaporation, maintain stable water level, prevent external pollutants from entering the system and ensure the quality of treated water.

[0035] Please refer to Figure 5 In use, the construction wastewater is discharged into the primary sedimentation tank 2 through the trench, and after preliminary sedimentation in the primary sedimentation tank 2, the supernatant in the primary sedimentation tank flows into the secondary sedimentation tank 32 through the collecting trough 22. In this process, the collecting trough 22 can filter out impurities floating on the water surface through the filter screen 221, and the wastewater in the secondary sedimentation tank 32 is again subjected to sedimentation. Since the partition wall of the overflow tank 31 is lower than the collecting trough 22, the liquid level of the secondary sedimentation tank 32 is continuously raised as the upper clear water is continuously injected, and the rising liquid level gradually flows into the overflow tank 31. At this time, fine solid impurities such as dust will appear again at the bottom of the secondary sedimentation tank 32, and the impurities of the wastewater entering the overflow tank 31 are further reduced.

[0036] The precipitated impurities in the primary sedimentation tank 2 can be discharged into the waste storage tank 4 through the pump set in the drain pipe 21, and the impurities in the secondary sedimentation tank 32 can be regularly cleaned by a mechanical excavator, and the cleaned impurities are also poured into the waste storage tank 4, so that the waste is collected.

[0037] The sewage in the overflow tank 31 is transported to the water purification device by the pump set, so that the sewage is mixed and stirred with the reagent to remove the odor; after the water purification treatment, the purified water is transported to the water storage tank for preliminary storage; due to the low overall setting elevation, when the water is used for construction, a booster pump is needed to transport the water in the water storage tank to the construction site for dust removal, equipment cooling and the like; and the used water forms sewage again and flows into the ditch, and then flows into the primary sedimentation tank again through the ditch, so that the water source can be saved, the dependence on external water source can be reduced, the sewage can be avoided from being discharged to the outside to affect the environment, and good economic and social benefits can be obtained.

[0038] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Other different forms of changes or variations can be made by those skilled in the art on the basis of the above description. All the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
